Question

Which of the following statements is true about bacteria?
Options
A They grow best at acidic pH.
B They all produce spores for reproduction.
C They have a cell membrane and cell wall.
Correct Answer
D All bacteria are aerobes.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Most bacteria possess both a cell membrane and a cell wall (except for Mycoplasma, which lacks a cell wall). Bacteria exhibit diverse pH preferences, not all produce spores for reproduction (spores are often for survival), and many are anaerobes or facultative anaerobes, not exclusively aerobes.

Hint

Recall the fundamental structural components common to the majority of bacterial cells.
